BUNG-HOLE STOPPER OR SEAL FOR METALLIC KEGS.

SPECIFICATION formingpart of Letters Patent No. 683,182, dated September24, 1901.

Application filed April 24, 1901.

To on whom it may concern.-

Be it known that I, JOSEPH H. MCCLEL- LAND, a citizen of the UnitedStates, residing at Wayne, in lVayne township, in the county of Passaicand State of New Jersey, have invented certain new and usefulImprovements in Bung-Hole Stoppers or Seals for Metallic Kegs, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

In metallic kegs or casks used for holding and transporting powder orother substances various methods have been devised for closing andsealing the bung-hole in the head of the cask. Plates provided with anopening somewhat smaller than the bung-hole have been secured to thehead of the barrel by turning the edge of the bung-hole over the edge ofthe hole in the plate to secure the plate to the head of the keg, andthe edge of the said plate, on three sides thereof, has been turned overto form a slide for a. sheet of metal or shutter, which is pushed intothe same, and the fourth side of said plate, being made longer than theshutter, is adapted to be bent over the end of the shutter-to secure theshutter over the bung-hole. That method of closing the keg has beenvaried by having two of the edges of the shutter turned over, so as toform a slide adapted to receive and pass around two of the edges of theplate, which is secured to the head of the keg, and the shutter issecured to the plate on the head of the keg by turning the ends of saidplate over the other two ends of the shutter. In both of the methodsabove mentioned considerable time, labor, and material are employed; andthe objects of myinvention are to accomplish the same purposes with lesstime, labor, and material and to provide a more perfect bung for thebung-hole in the head of a metallic keg and one that will not projectabove the head of the barrel so as to present an object for contact withobstacles in the handling of the keg and which will at the same timeprevent the leak or escape of powder or other explosive materials fromthe keg. I attain these objects by means of the barrel-head, bung-hole,and stopper or seal, arranged as hereinafter described and shown, andillustrated in the accompanying drawin gs, which are made part hereofand in which Serial No. 57,426. (No model.)

similar parts are similarly indicated in the' drawings.

Figure 1 is a top plan View of my bung secured in the bung-hole of abarrel-head. Fig. 2 is a vertical transverse section of the same on linea; 00, Fig.1, inverted; and Fig. 3 is a top plan view ofthe bung.

Like numerals of reference indicate like parts throughout the drawings.

4 is a metallic bung which is formed like a shallow dish and providedwith an annular flange 5.

6 is the head of a cask, keg, or barrel, also metallic, through which isa circular opening or bung-hole, around the edge of which bung-hole isan annular depressed portionof the head 6, adapted to receive theannular flange 5 of the bung, which is formed to fit into said annulardepressed portion.

8, 9, and 10 are tongues forming an integral part of the head 6 andadapted to be raised while the bung 4 is placed in the bunghole, thelower depressed portion of the bung passing through and fitting snuglyin said bung-hole and its annular flange 5 resting in the annulardepressed portion of the head 6, which surrounds the bung hole. Thetongues are adapted to be hammered down over the annular flange of thebung. The tongues 8, 9, and 10 when raised leave openings in the head 6,which are covered bythe annular flange 5 of the bung. The depressedportion 11 of the bung, which is shown inverted in Fig. 2, fits snuglyinto the circular opening or bung-hole in the head 6. The vessel is thustightly sealed, and the prevention of the leakage or escape of thecontents is insured.

While my invention relates particularly to metallic casks for holdingand transporting explosive substances, it is obvious that it may beemployed also for other purposes and that minor changes may be made andalterations 5 in the construction Without materially departing from theessential principles or scope of my invention. For instance, a can forcarrying milk or other liquids might be provided with my invention, anda wooden cask could be fitted with a metallic rim or bushing around thebung-hole, having a depressed portion provided with tongues adapted toretain a bung, as above described.

When it is desired to remove my bung, one or more of the tongues arepried upwardly. The dished portion of my bung may be shallow orotherwise, as desired. The bung-hole in the top or end of a metalliccask or barrel and the depressed annular portion around the bung-hole,as well as the tongues which are cut integral with the top or end of thevessel, are all made by me in one operation by a combination-die, whichpresses the niaterial, cuts out the bung-hole, and cuts the tongues,forcing one of them downwardly into a vertical position and the othersdownwardly at an angle. It is obvious that the flange of the bun-g maybe inserted readily under two of the tongues and will rest upon thedepressed surface surrounding the bunghole, when the three tongues maybe hammered down over the flange of the bung, tightly sealing the keg orother vessel;

With this description of my invention,what I claim is-- 1. In a metallicvessel, a closing device consisting of the head having acentrally-depressed portion, provided with an opening or bung-hole,which is formedby cutting a piece out of said depressed portion, leavinga flat annular edge around the bung-hole at the bottom of the shoulderswhich are formed by depressing the central portion of the head, andtongues cut out of, and integral with, the said flat annular depressedportion surrounding the bung-hole, and raised upwardly to permit theinsertion under the same of the edge of a metallic bung, in combinationwith a metallic bung formed like a shallow dish having a'sunken portionadapted to fit snugly eeeu into the said bung-hole, and provided with anannular flange adapted tovrrest on the anf "9 nular flat depressedportion of the head which 4e 1, surrounds the bung-hole, to cover theopen- I ings made by raising said tongues, and tobe held there in placeby the lowering of said I tongues down over the annular flange of the Vbung below the level of the top of the vessel; :f substantially as setforth.

Inavessel foreirplosives;ametallicheadg" V v I providedwith a circular opening, and an an' V nular depressed portionsurrounding said 7 opening, two or more tongues cut out of, and formingan integral part of, said annular de- V pressed portion surrounding saidopening, in.
